Why did Russia go to war with Ukraine?

At present, there is no war between Russia and Ukraine, but the relationship between Russia and Ukraine has been tense since the political turmoil in Ukraine on 20 14.

20 14 A political crisis broke out in Ukraine, and President Yanukovych was forced to step down because of his policy toward Russia. Subsequently, the pro-European government of Ukraine came to power, and Russia expressed strong dissatisfaction. Russia believes that Ukraine's pro-European government has the support of western countries and tries to lead Ukraine to the west, which poses a threat to Russia's interests.

On March 20 14, Russia sent troops to Crimea and incorporated it into Russian territory through a referendum. This move has aroused widespread concern and condemnation from the international community, and the Ukrainian government and western countries have strongly protested against it. Since then, the pro-Russian civilian armed forces in eastern Ukraine have been upgraded to all-round anti-government armed forces, and there have been many fierce conflicts between the Ukrainian government and pro-Russian armed forces. Although the two sides have tried many times to resolve the dispute through peace talks, they have not reached a lasting peace.

Therefore, although there is no formal war action at present, the tension between Russia and Ukraine still exists and needs the sustained attention and efforts of the international community to ease it.
